tl;dr: For many types of GL object, we can *NEVER* use the Gen function.
In OpenGL ES (all versions!) and OpenGL compatibility profile,
applications don't have to call Gen functions. The GL spec is very
clear about how you can mix-and-match generated names and non-generated
names: you can use any name you want for a particular object type until
you call the Gen function for that object type.
Here's the problem scenario:
- Application calls a meta function that generates a name. The first
Gen will probably return 1.
- Application decides to use the same name for an object of the same
type without calling Gen. Many demo programs use names 1, 2, 3,
etc. without calling Gen.
- Application calls the meta function again, and the meta function
replaces the data. The application's data is lost, and the app
fails. Have fun debugging that.

The fixed-function attribute paths don't get the DSA treatment because

(cherry picked from commit 4e6b9c11fc)
Instead of going through the GL API implementation functions, use the
lower-level functions. This means that we have to keep track of a
pointer to the gl_buffer_object and the gl_vertex_array_object.
This has two advantages. First, it avoids a bunch of CPU overhead in
looking up objects and validing API parameters. Second, and much more
importantly, it will allow us to stop calling _mesa_GenBuffers /
_mesa_CreateBuffers and pollute the buffer namespace (next patch).

As of last few commits we have a static and dynamic pipe-loader. Either
of which will be used with (almost) all targets..
We can look into allowing the user to select which way the targets are
built, be that 'static for all' or 'per target' in follow up commits.
After which we can look into building only the static or dynamic
version, although building both shouldn't cause any issues.
Hack/workaround alert:
Control the standalone pipe-drivers via HAVE_CLOVER. Will need to be
fixed as the targets are converted/configure knobs are in.

It is to be used in contrast of the dynamic one. The state-tracker does
not need to know if the pipe-driver is built into the final blob or
a separate object. This will allow us to move the logic to the final
step (in target) where the appropriate pipe-loader will be chosen.
